Very impressed with these lights. No, its not a BLF, Convoy, Nitecore, or Klarus quality, but only a notch below imo. Although 1/4 the price, none of those lights are 4 times the light the Nitenumen is. The way it comes in a nice box with a protected Panasonic 3400 battery, extra oring, lanyard, extra charge port plug, belt clip and a decent belt velcro pouch, Perfect for gifts. I've got a lot more expensive lights not packaged nearly as well...
Good quality, good anodizing, and heavy solid construction. Reflector is smooth and deep, producing a great long distance spot beam with lots of flood spill over. Didn't test lumens, but lights seem to be on par with my other 1000 lumen lights. A bright light for sure, cool white, maybe 6500 Kelvin or so. No detectable blue tint like many fake cree low price lights. I believe this to be a real cree emitter.
Tail and side switch seem to operate smooth and crisp, with a positive action. Although not square cut threads like Convoy, the threads are amazingly smooth and well cut. Maybe feel better that some square cut threads. Driver and tail switch are held in place with a brass threaded keeper, no plastic press fit keepers. Unusually good construction for a cheaper light imho.
Tested out to 2.8amp draw on highest setting. Battery is a 3400 protected button top Panasonic rewraped. All 4 of mine tested out to between 3091 to 3132 mAh with low ir. I assume without the protection circuit, not allowing them to be discharged fully, they would've been closer to the 3400mAh listed for Panasonic...
As these lights are new to me, with no long time owner experience, hoping they hold up like they seem to be early on. With the seemingly good construction and parts used I don't see why they wouldn't, but time will tell...
Might try to mod 1 of them with an XHP50.2 I've got hanging around and a driver capable of Narsil. Wondering if anyone has tried this..?
